DISPOSABLE DIAPER

摘要

A disposable diaper using elastic sheet materials so that a contact surface pressure may be locally enhanced and thereby the diaper may be prevented from being noticeably displaced on the wearer's body during used thereof is provided. Of first and second waist regions 13, 14, at least the first waist region 13 is contractible. The first waist region 13 includes waist auxiliary elastic sheets 24A, 24B extending in a direction of a transverse axis Q between opposite side edges 18c, 18c of the first waist region 13 and leg auxiliary elastic sheets 26A, 26B extending along front peripheral edges 18d, 18d of leg-openings. The waist auxiliary elastic sheets 24A, 24B and the leg auxiliary elastic sheets 26A, 26B overlap one another in areas of the opposite side edges 18c, 18c of the first waist region 13 adjacent to the leg-openings 17a, 17b, respectively. With the diaper put on the wearer's body, these areas come in contact with upper lateral regions of the wearer's iliac bones inclusive of the vicinity thereof.
